The value of pulse constant should satisfy following formula(Only used in
Acuvim II):
Pulse constant >( +1) ×
In the formula, “Pmax” is the maximum power or reactive power. The unit is
watt or var. Recommend pulse constant is 3 to 5 times the right side value of
the above expression.
5.1.10 Analog Output
1. Analog Output Relationship with Electrical Quantities
The analog output circuit can convert anyone of 30 electrical quantities
(reference Chapter 6), which is selected by user, to analog voltage or current.
The analog output circuit supplies 4 output modes, including 0 to 20mA mode,
4 to 20mA mode, 0 to 5V mode and 1 to 5V mode.
Figure 5-20 shows the relationship between analog output and various
electrical quantities.
